ably deeper than the rear end to provide In the hot-air pipes 10 there maybe provided any required number of perforations 2O for properly distributing hot air throughout the drier during the sifting operation.

By reference to Fig. E. it will be observed that passages or openings 2l, 22, and 23 are provided at the lower ends of the successive inclined sifters 5, 6, and 7, so that during the sifting operation lumps can rollfreely from the surface of an upper sifter onto the next lower one and from the lowest sifter into the trough l1, and thence to abarrel or other re ceptacle. Meanwhile by the oscillations of the box 1 the sifting ofthe fine sugar is greatly7 facilitated, and it finally passes from the inclined bottom of the box through the outlet l2 to any receptacle that may be provided for its reception. During the sifting operation the sugar is thoroughly dried out by contact with the het air forced into the sifting and drying box. The sifted sugar is dry, bright, and lustrous and will keep indefinitely without becoming caked or lumpy.

That we claim as our invention isl. In a sugar drier and sifter, the combination of an oseillatorybox, a series of inclined Sifters arranged in said box one above another with an opening` at thelower end of each sifter for passage of lumps and scales from the uppermost sifters to the lowerniost sifters, in succession, a trough leading from beneath the lowermost of said openings to and through the side of said box to discharge the lumps and scales, au outlet for sifted sugar, and means for distributing hot air through said box to dry the sifted sugar, substantially as described.

2. In a sugar drier and sifter, the combina-- tion of an oscillatory box provided with an inclined bottom and having a hopper-inlet at the top, a series of sitters arranged in said box one above another and successively inclined in reverse directions7 the said sifters being provided at their lower ends with openings or spaces for passage of lumps and scales from one sifter to another, an inclined trough for discharge of lumps and scales from the lowermost of said passages to the outside of the box, an outlet for discharge of sifted sugar from the inclined bottom of the box, and series of perforated hot-air pipes arranged in and movable with said box for drying the sugar during the sifting operation, substantially as described.

3. In a sugar drier and sifter, the combination of an oscillatory box having a hopperinlet at the upper portion of one end and pro- ,vided with an inclined bottom, a series of rcversely-inclined sitters in said box one above another and each provided at its lower end with an opening for passage of lumps and scales, a trough for discharge of lumps and scales from beneath the lowermost of said openings, an outlet for discharge of sifted sugar from the inclined bottom of said box, perforated pipes arranged in. said box for distribution of hot air therein, means for suspending the said box, and mechanism for oscillating the box, substantially as described.

In testimony whereof we have hercun to subscribed our names in the presence of two wit nesses.
